The receptacle has nothing to do with how much current is drawn, what is plugged into the receptacle does.True but the face plate of the receptacle configuration determines what plug can be connected to it.

The max continuous load that a NEMA 5-15P can carry by NEC code is 12 amps.
For a NEMA 5-20P plug it is 16 amps.
NEC says for a 120V 15 amp branch circuit the receptacle must be a 15 amp rated receptacle. Reason being so a piece of equipment with a 20 plug cannot be plugged into it.
As I said in my ealier post, the 20 amp recept did not cause the problem.
